Publication Open Access Growth Arrest-Specific 6 and Cardiometabolic Risk Factors in Patients with Psoriasis(WILEY, 2015-04) SEÇKİN GENÇOSMANOĞLU, DİLEK; Sunbul, Murat; Cagman, Zeynep; Gerin, Fethullah; Ozgen, Zuleyha; Durmus, Erdal; Seckin, Dilek; Ahmad, Sarfraz; Uras, Fikriye; Agirbasli, MehmetObjectivesAn increased risk for cardiovascular disease with psoriasis has been reported. Growth Arrest-Specific 6 (GAS6) amplifies pro-inflammatory endothelial cell activation via TAM receptors. However, it also inhibits inflammation by multiple mechanisms including phagocytosis. The objective of this study was to investigate whether plasma GAS6 levels are associated with conventional cardiometabolic (CM) risk factors in patients with psoriasis. MethodsForty patients diagnosed with psoriasis (22 male, mean age: 43.313.8years) and 40 age-/sex-matched healthy controls (22 male, mean age: 39.38.9years) were included in the study. CM risk factors (hypertension, hyperlipidemia, diabetes mellitus, and cigarette smoking) were identified. GAS6 levels were measured by ELISA. ResultsThere were no significant differences between the plasma GAS6 levels of patients with psoriasis compared to the control group (6.6 +/- 2.0ng/mL, 7.6 +/- 2.8ng/mL, respectively, P>0.05). However, GAS6 levels of patients with psoriasis having a smoking history (n=11) were significantly lower than both patients with psoriasis who had no smoking history (n=29) and controls (5.5 +/- 1.7ng/mL, 6.9 +/- 1.9ng/mL, 7.6 +/- 2.8ng/mL, respectively, P<0.05). Similarly, psoriasis patients with at least one CM risk factor showed lower GAS6 levels compared to subjects without any CM risk factor (5.7 +/- 1.7ng/mL, 7.3 +/- 2.0ng/mL, P<0.01). There was no correlation between the GAS6 level, disease duration or PASI score (r=0.150, -0.150, and P=0.310, 0.398, respectively). ConclusionsThis pilot study provides the first evidence in humans for an association between low plasma GAS6 levels and conventional risk factors in psoriasis. Further large scale, prospective studies are needed to confirm these results.Publication Metadata only Assessment of left atrial volume and function in patients with psoriasis by using real time three-dimensional echocardiography(SPRINGER WIEN, 2015) ÇİNÇİN, AHMET ALTUĞ; Atas, Halil; Kepez, Alper; Bozbay, Mehmet; Gencosmanoglu, Dilek Seckin; Cincin, Altug; Sunbul, Murat; Bozbay, Ayfer Yildiz; Darvishova, Ramila; Ergun, TulinBackground Left atrial (LA) volume has been identified as a predictor of adverse cardiovascular outcomes, both in the general population and in selected clinical conditions. The aim of this study was to evaluate the effect of psoriasis on LA volume and mechanical function. Methods A total of 40 consecutive normotensive psoriasis patients free of any cardiovascular disease and 39 healthy volunteers were included. All participants underwent comprehensive transthoracic echocardiographic examination. LA volume and mechanical function were evaluated using real-time three-dimensional echocardiography (RT3DE). Results There were no significant differences between psoriasis and control groups with regard to conventional echocardiographic parameters. Individuals with psoriasis had a higher incidence of left ventricular diastolic dysfunction (LVDD) than the controls; nine people with psoriasis (23 %) and three control individuals (8 %) had LVDD (p = 0.06). With regard to the parameters obtained from RT3DE, LA maximum, LA minimum, passive stroke volume, and passive emptying fraction were significantly higher; whereas LA active emptying fraction, LA total emptying fraction, LA expansion index, and active stroke volume values were significantly lower in individuals with psoriasis compared with controls. Disease duration and Psoriasis Area of Severity Index (PASI) score correlated with the majority of volume parameters. Conclusion Individuals with psoriasis had higher LA phasic volumes and impaired LA mechanical function compared with healthy controls. LA volume and functional analysis with RT3DE may facilitate recognition of subtle LA dysfunction in patients with psoriasis.Publication Metadata only Assessment of arterial stiffness and cardiovascular hemodynamics by oscillometric method in psoriasis patients with normal cardiac functions(SPRINGER, 2015) SEÇKİN GENÇOSMANOĞLU, DİLEK; Sunbul, Murat; Seckin, Dilek; Durmus, Erdal; Ozgen, Zuleyha; Bozbay, Mehmet; Bozbay, Ayfer; Kivrak, Tarik; Oguz, Mustafa; Sari, Ibrahim; Ergun, Tulin; Agirbasli, MehmetArterial stiffness is associated with increased cardiovascular risk. Pulse wave velocity (PWV) and augmentation index (AIx) are non-invasive markers for assessment of arterial stiffness. Increased arterial stiffness is associated with atherosclerosis in patients with psoriasis. Previous studies have shown that high neutrophil-to-lymphocyte ratio (NLR) predicts poor cardiovascular outcome. The aim of this study was to evaluate arterial stiffness and cardiovascular hemodynamics by oscillometric method in psoriasis patients with normal cardiac functions. Fifty consecutive patients with the diagnosis of psoriasis and 50 controls were included in the study. NLR was calculated as the ratio of neutrophil count to lymphocyte count. All patients underwent echocardiographic examination. Measurements of arterial stiffness were carried out using a Mobil-O-Graph arteriograph system. Fifty patients with psoriasis (26 male, mean age 43.3 +/- 13.2 years) and 50 controls (33 male, mean age 45.0 +/- 6.1 years) were included into the study. The distribution of cardiovascular risk factors was similar between the two groups, and NLR was significantly higher in patients with psoriasis (2.74 +/- 1.78 versus 1.82 +/- 0.52, p = 0.002). There was a weak correlation between NLR and PASI score without reaching statistical significance (r = 0.300, p = 0.060). While echocardiographic and hemodynamic parameters were comparable between psoriasis and control groups, heart rate was significantly higher in psoriasis group (81.5 +/- 15.1 and 75.2 +/- 11.8 beats/min, p = 0.021). Psoriasis patients had significantly higher AIx and PWV values as compared to controls (25.8 +/- 13.1 versus 17.4 +/- 12.3 %, p = 0.001 and 6.78 +/- 1.42 versus 6.18 +/- 0.80 m/s, p = 0.011, respectively). AI and PWV were significantly associated with psoriasis when adjusted by heart rate (p = 0.005, odds ratio 1.04, 95 % confidence interval 1.01-1.08 and p = 0.035, odds ratio 1.52, 95 % confidence interval 1.02-2.26, respectively). PWV significantly correlated with blood pressure, lipid levels, and several echocardiographic indices. AIx only correlated with left atrial diameter (r = 291, p = 0.040). Linear regression analysis was performed to find predictors of PWV. Central systolic blood pressure, left atrial diameter, and total cholesterol were independent predictors of PWV. PWV and AIx were significantly higher in patients with psoriasis. Assessment of arterial stiffness parameters may be useful for early detection of cardiovascular deterioration in psoriasis patients with normal cardiac functions. Novel inflammatory biomarkers such as NLR may elucidate the mechanism of vascular dysfunction in such patients.
